4th gen Oil Change

How many miles do you put on in a year? 10k mile oil intervals is too long, unless you're doing it in like 6 months.

 

@Johnny919 What real world benefits would SailorChris have seen from performing oil changes at 5k instead of the stated 10k interval throughout the 225k miles on the truck?

 

Less likely to have sludge/carbon deposits build up. In general just having a cleaner engine.

 

For proof of oil change, either pictures or video of the dash mileage and drain sequence
along with receipts of oil/filter and date will be enough if ever contested

 

Those may be true, but seem to be just perceptual / peace-of-mind things rather than truly functional benefits.

 

The great bulk of the old Ranger's mileage is on the highway at moderate speeds. My daily work commute is usually by bicycle so there's not a lot of short-trip driving at cold engine temps. The engine has never needed service so I haven't seem its innards except what's visible down the oil-fill hole, but it shows no signs of being sludged-up. I've figured that a high-quality synthetic oil plus favorable operating conditins justified the extended interval I've taken the fact that it burns no oil at 225,000 miles supports the hypothesis. Consider also that this is in Michigan, where vehicles commmonly turn to rust before the engine shows signs of impairment. I had considered finding a solid southern truck and oing an engine/transmission transplant but life is too complicated to accomplish that right now. It might be interesting to get an oil analysis on the Rager to see what it shows.

Meanwhile, I'll stick with the Toyota recommended interval to protect the warranty.

 

I trust this guy. He's worth listening to.

This is how I document my oil changes–on the Fuely app.



It's generally for my own knowledge, but in the event I ever have to prove I maintained it, it's there.

 

No way you'll catch me doing 10k mile intervals on a turbo engine that turbo is cooking the oil in a way an NA engine never will.

It might not be a problem for 10k miles but why not do 5k interval. Don't forget, air and engine oil filters aren't perfect. Stuff will get through them, the next best thing you can do is a short-ish interval. Virtually everyone falls under Toyotas "severe" OCI, thanks to everyone being stuck in stop and go traffic and idling their trucks for extended periods (drive thru).

 

All I know is ever since manufacturer's started extending oil change intervals and started using thinner oils like 0w20/16 etc we are starting to see nothing but problems all across the board.

Although there are several factors lole Sailorchris mentioned, how the vehicle is driven etc

 

Or not...

I think people are just too broke to do their usual consumer bs of buying a new car every other year so they're keeping and repairing their cars.

If you don't keep a Toyota for 10 years you're crazy anyways lol or if you lease one.

 

Problems across the board? Please provide links to those.

In my case, 103k miles over nine years next month and zero issues. Lots of short trips, plenty of longer drives. 10k synthetic changes. When should I expect to see these problems?

FWIW my wife’s RAV4 made it 140k miles with no issues until totaled from a rear end hit and run.

So I’m just curious as to the fact/example basis for your recommendation

 

Yeah, I'm not getting that supposition, either. My totally-not-scientific study of reading about what's going on with cars in general on the internet, hearing what mechanics say, etc, says otherwise. If you're going to say that there's "issues across the board," the "issues" usually stem from bad design decisions and sloppy manufacturing. We've had some pretty famous examples of issues due to lazily cleaned castings in regards to Kia Theta engines and Toyota V6 Tundra engines, and, to a much lesser extent, the early 4G Tacoma transmissions. A couple manufacturers have had issues stemming from the choice to use low-tension piston rings leading to oil consumption. Stellantis has issues with cams wearing on their V6's, which seems to be more about poor oiling and materials choices for rockers rather than oil type. GM and Stellantis continue to have issues with lifters because of poor design choices for cylinder management on their V8's. Ford and VAG can't seem to make good materials choices for timing components to save their lives.

Off the top of my head, I can only think of one example of a manufacturer needing to back off the 0W20 spec to something else, with GM switching the 6.2L V8 to 5W30. Honestly, I think that's just going to cover up issues for long enough to get them out of warranty, as I suspect the issue probably stems — again — from poor design or materials choices.

Let's call the hand-excavation tool here what it is: every time the "common" oil spec changes, there's great wailing and gnashing of teeth. Old men cried foul when multi-viscosity oil became the norm and they swore using SAE30 in the winter and SAE40 in the summer would save their engines from horrible deaths. All over the country, pearls were furiously clutched as 10W30 and 10W40 gave way to 5W30. Tears were shed as 5W30 made room for 0W20. Now we have 0W16 and even 0W8. Statically speaking, engines last longer and run more efficiently now than they ever did, "watery" oil notwithstanding. Your engine isn't going to blow up because you used the oil the manufacturer specified for it.

 

Took my wife's Camry in today for her 20K free service. It was weird. They text you your "vehicle report". They reported both the cabin filter and engine air filter were dirty "check at next service". Yet when I got home and decided to look at the receipt they changed the cabin filter (for free) and did not change the engine air filter.

We will see how my 20K service goes next week on the Tacoma and see if they do the same.

Those are manufacturing issues, not caused by oil change intervals. The Tundra engines had machining debris left inside, and the GMC engines have out-of-spec cranks.

 

Moving from 0w20 to 0w40 as part of remedy.

Gm moving from 0w20 to 0w40 as part of remedy for engine failure.

I'm not saying just extending oil change intervals is the problem, but it's certainly one of them.

Thanks. Interesting articles. 39 complaints of connecting rod / camshaft on GMs. Undisclosed quantity of Tundra with & Lexus LX motors with machining debris not cleared during production.

How again are these related to the benefits of a 5k vs 10k OCI on a Tacoma?
